OSCAR R. RYDQUIST, OF ST. CROIX FALLS, WISCONSIN.

OIL-CAN.

To all whom it may concern Be it known that I, OSCAR R. RYn UIsT, acitizen of the United States, residing at St. Croix Falls, in the countyof Polk and State of lVisconsin, have invented certain new and usefulImprovements in Oil-Cans; and I do hereby declare the following to be a.full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to oil cans of the class wherein the operatorforces oil through the spout by pressure, as will be apparent from thefollowing specification, reference being had to the accompanyingdrawings which are made a part of this application in which,

Figure 1 is a central longitudinal section, Fig. 2 is an end view, Fig.3 is a plan View of the piston.

In the detailed description of my invention numerals will be used todesignate the various parts, the same numeral being used for the samepart throughout.

My invention consists of an oil can of which the body portion 1, ispractically divided into two chambers 2 and 3 by a piston 4: therelative size of the chambers being governed by the position of thepiston therein. Said piston is connected by a pistonstem 5 to a. handgrip 6. A valve 7 is hingedly mounted on said piston to permit the oilto flow from chamber 2 to chamber 3. The piston is made wedge shaped,its upper edge being a little thicker than the diameter of the openingto the spout, to furnish a. closure for said opening to prevent thesiphoning of the oil from the can when held suspended in the hand. Thewedge shape is preferred, to save weight and material in theconstruction thereof. A spiral spring 8 is mounted on the piston stem tohold the piston in and return it to its inwardly normal position whennot controlled by pressure of the fingers on the hand grip 6.

A tapered spout 9 is connected by screw threads to the top side of thecan and it extends along said side parallel thereto and beyond the frontend thereof. Legs or supporting members 10 are fastened tothe bottomside of the can to prevent its rolling when lying on its side. A handle11 is vertically positioned on the rear end of the can, extending backfrom the end of the can a sufiioient distance to permit the hand-grip 6Specification of Letters Patent.

to be moved rearwardly the full length of the piston stem 5. At onesideof the handle a guiding groove 12 is formed by pressing inwardly theedges of said handle and one end 13 of the hand-grip is slidably mountedin said guiding groove to prevent the hand grip from rotating thusmaintaining it in its operative position.

For the purpose of filling the can an opening 14, having a threadedclosure 15, is provided at the forward end of the can, said closurehaving an extension 16 through which an aperture 17 is formed to furnisha means for hanging up the oil can if desired. A spring controlled valve18 is provided on the upper side of the front end of the oil can topermit air to enter therein.

On the inside of the can a plurality of stops 19 are placed to controlthe distance which the piston may be moved. Vhere the piston stem passesthrough the end of the can a stufiing box 20, having a threaded cap 21,is provided to prevent the leaking of oil.

In operating the oil can, the chamber 2 is filled with oil through theopening 14. The gil flows through the valve 7 into cham- When in use thecan is held horizontally in the hand by grasping the handle and the handgrip 6. When it is desired to force the oil out, a slight tightening ofthe grip of the hand will pull the piston-stem out and cause a pressureto be exerted on the oil in chamber 3 by the piston and thus force itout of the spout at the will of the operator.

The peculiar arrangement of parts in the location of the handle andspout, and the spout being attached by screw threads, permitting it tobe turned at an angle with the body portion if desired, will enable theoperator to oil bearings located in places practically inaccessible toan ordinary form of oil can.

Having thus fully described my invention in the foregoing specificationsand illustrated in the accompanying drawings the preferred constructionand combination of parts deemed necessary in materializing my invention,I wish it understood that I wish to comprehend in this application allsubstantial equivalents and substitutes which may be considered asfalling fairly within the scope of my invention.

What I claim and wish to secure by Letters Patent is:

1. An oil can comprising an oblong cylindrical body portion of uniformdiameter throughout its length, a spout removably secured to said bodyportion adjacent one end thereof and normally disposed parallel with thebody, a piston of a diameter equal to the diameter of the body portion,said piston being greater in width at one edge than at the other, a stemattached to the piston and extended through one end of the body portion,a hand-grip attached to said stem, a spring surrounding said stemwhereby the piston is held normally inward, a valve pivotally secured tothe piston, a guide for said hand-grin. an air vent for said bodyportion, and a plurality of stops adapted to limit the movement of thepiston in the body portion.

2. The combination with an oil can; of a wedge shaped piston, having asuitable valve operatively mounted therein and connected by a stem to ahand-grip; a plurality of stops fixedly placed upon the inside of thebody portion; a spiral spring surrounding the piston-stem; a handlemounted on the end of the can; a guiding groove within the said handle;a hand-grip attached to the piston stem and having one end of saidhand-grip slidably mounted in said groove; a spout operatively fastenedto and normally extending parallel with the top side of said can;supports on the lower side of said can whereby it is kept in properposition when not in use, and an air vent on the upper side of the frontend of said oil can.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
